Mr George Michaelson (APNIC)


APNIC has been conducting a long lived (5 year) measurement activity using google ads and javascript placements worldwide. We collect over 700,000 experiments a day from end users. The sampling is random, but has placement bias. So, we've developed methods of adjusting for this using world population stats. A side effect of this is that we may now have one of the only public insights into relative market share in the ISP community worldwide, and inside each economy.


A presentation based on work I've given to Regional RIR meetings, which explores how APNIC measures end user V6 and DNSSEC capability. Its about 50 slides, its about 30 minutes of presentation.
